During his monologue, host Jimmy Kimmel mentioned the 2017 Best Picture gaffe. The cameras cut to "La La Land" star Emma Stone, who was part of the *almost* winning team, and a key name in the ensuing snafu.

Emma Stone had talked about the gaffe backstage during the 2017 show, right after she won Best Actress for "La La Land." Her name came up again because it was the name in the envelope Warren Beatty had been given, instead of the correct Best Picture envelope reading "Moonlight."

So when Jimmy Kimmel brought up the gaffe again, Emma Stone looked a bit abashed -- and her BFF Jen was all over it, laughing in her face as all true friends would.
